Thanks! We’ll be in touch with you soon.

We've blogged before about starting the CLM components on Linux/Unix. Now let's talk about staring it (and stopping it) on Windows platforms. The vast majority of the servers we deploy to are Linux.

During some courseware authoring I discovered a poorly known (but sufficiently documented) feature in Rational Developer for IBM i (and also available in IBM Developer for System z). Both tools use the LPEX editor as the default editor for source (although IDz has dedicated editors for COBOL, JCL, PL/I, and C/C++). The LPEX editor has…

In a recent project for a z/OS customer, we had to create some custom scripts to kick off a Rational Team Concert Promotion definition. This is a special type of build definition found in the RTC Enterprise Extensions, and is used for promoting change sets from one stream to another, by their attachments to work…

Why you should change the default certificates? If you are a user of IBM Rational Team Concert, DOORs Next Generation, Quality Manager, Design Manger, or Engineering Lifecycle Manager, you likely have seen the issue with the browser stating "Your connection is not private", and red error showing in the browser URL as 'Not Secure'. If…

I recently ran across an issue, one that was low priority, but nagging like a gnat on a hot summer day. I kept seeing these entries in the log files: ERROR ervice.internal.GlobalConfigurationCacheUpdateTask - [operationId=976] com.ibm.team.jfs.app.http.HttpServiceUnavailableException: Unable to discover the GC service, which might indicate that Global Configuration Management is not set up in JTS.
